ABSTRACT:
FIELD OF THE INVENTION
Sagittaria australis
‘Benni’ is a herbaceous ornamental aquatic perennial suitable for the water garden market.
DESCRIPTION OF RELEVANT PRIOR ART
The following chart summarizes some of the differences between
Sagittaria australis
‘Benni’ and the plant it most closely resembles,
Sagittaria australis
(common Appalachian arrowhead) under the same cultural conditions. Color designations are compared to the 1986 edition of R.H.S. Colour Chart, first published in 1966 by The Royal Horticultural Society, London, England.

A sport seedling was found growing among cultivated
Sagittatria australis
(common Appalachian arrowhead). The plant was asexually reproduced in the greenhouses of Aquascapes Unlimited, Pipersville, Pa., by way of bare tuberiferous root division of a vegetative stock plant. By subjecting clones of this plant to successive generations of vegetative propagation, it was demonstrated that the distinctive characteristics of
Sagittaria australis
‘Benni’ held true from generation to generation.
SUMMARY OF THE INVENTION
This new
Sagittaria australis
cultivar was found growing among straight species of
Sagittaria australis
in my greenhouse in Pipersville, Pa. It was selected because of its greyed-purple leaves with green venation; greyed-purple bracts at the axil, from which the flower stalk arises; and greyed-purple sepals; traits that distinguish it from other cultivars of
Sagittaria australis.
These traits seem to make the plant desirable for commercial ornamental aquatic production, as the plant should be desirable as a decoration in ponds. After selection,
Sagittaria australis
‘Benni’ was vegetatively reproduced from root cuttings for test purposes in my greenhouse in Pipersville, Pa.
Sagittaria australis
‘Benni’ most closely resembles
Sagittaria australis
(common name Appalachian arrowhead), but differs in that
Sagittaria australis
‘Benni’ has greyed-purple leaves with green venation, greyed-purple bracts, and greyed-purple sepals, whereas
Sagittaria australis
leaves and bracts are green.
